DOOR SEAL ASSEMBLY 2 Sheets-Sheet 2 Filed Nov. 50, 1945 INVEN TOR.

Patented July 20, 1948 This invention relates to seating spring loadeddoor seal, which is especially designed to restrict the flow of dust,air, water and temperature around the door installation.

An object of the inventioniis to provide a'delvice that can beinstalledinhorizontal vertical or curved positions and which will becomemore eflicient through usage as the moving parts will more efiicientlyseat themselves through wear.

1 'Another object of the invention is to provide a device that is simplein construction, efficient in operation, durable in use and can bemanuiactured at a low cost.

With the above and other objects and advantages in view the inventionconsists of the novel details of construction, arrangement andcombination of parts more fully hereinafter described, claimed andillustrated in the accompanying drawings in which:

Figure 1 is an elevational view of the device as applied to bottom of aconventional door.

Figure 2 is a sectional view on the line 2-2 of Figure 1, with thedevice in contact with the door sill.

Figure 3 is the same as Figure 2 out of contact with the door sill.

Figure 4 is an elevational plate.

Figure 5 is a perspective view of the method of installation.

Figure 6 is a perspective view of the housing, and

Figure '7 is a perspective view of the moving part of the device.

Figure 8 is a detail showing a section through a lower corner of theretainer box showing the fabric hinges for mounting the bafiie plates.

Referring more in detail to the drawings the numeral l0 designates aconventional door having the bottom edge l2 in which is provided alongitudinally extending recess M which is adapted to receive therectangular shaped retainer box I6, which is provided on its bottom wallwith the longitudinally extending guideway slot l8,

Secured to the top wall of the box It by means of screws 20 which alsoretain the box in the recess H are the inverted U-shaped springs 22.

Positioned intermediately the legs of the springs 22 are thediametrically opposed longitudinally extending bafiie plates 24, whichare retained in alignment by means of the compression of the legs of thesprings 22 thereon.

The bafile plates 24 are attached to the opposite lower corners of thebox It by fabric hinges 26 view of the retaining a self-aligning, self-'3 which is made by cutting off noon SEAL ASSEMBLY I .gcla rlce QCufleLoraiJn, Ohio 7 Application November 30, 1945.

(o1. 2 o-'-s's)- .thus providing a-dual seal againstair enteringthe box'andthrough-the door Positioned intermediate the baffles 24 isthe seal 28,-which is substantially U-shaped in cross-section' havingthe longitudinally extending rib or tongue 30 on the base thereof whichextends through the slot IS in the box to contact the door sill 32 asshown in Figure 2. The shape of the seal 28 formslongitudinally-extending bulging shoulders 34, which-are diametricallyopposed on opposite sides of the tongue 30 and contact the lower wall.of the box on opposite sides of the slot l8, thus providing a tripleseal for the door.

The baffles contacting the legs of the seal not only prevent air frompassing through the seal but force the seal into close contact with thedoor sill.

The seal can be cut in segments and joined by an adhesive fabric 36moulded to the inner wall to allow for sag alignment of worn sills orcurved installation as shown in Figure 7 and plates 38 secured to thedoor by screws 40 close the ends of the box IS.

The box retainer can outside faces of the doors be made to extend to thefor old installations the required amount of the overall length of thedoor.

It is believed that the operation and construction of the device will beapparent to those skilled in the art and it is to be understood thatchanges in the details of construction, arrangement and combination ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claims.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

l. A weather sealing element comprising an elongated box-like casinghaving a longitudinally extending slot in the lower surface, a U-shapedtongue positioned in said slot and projecting therethrough with armsthereof bulging outwardly to form shoulders and extending upwardly andinwardly in said casing, inwardly inclined side plates mounted in thelower corners of the casing and positioned against the inwardlyextending ends of the arms of the tongue, and means resiliently urgingsaid side plates against the arms of the tongue whereby the tongue isresiliently held outward.

2. A weather sealing element comprising an elongated box-like casinghaving a centrally disposed longitudinally extending slot in the lowersurface, a U -shaped tongue positioned in said slot and projectingtherethrough with arms thereoi bulging outwardly to form shoulders andextending upwardly and inwardly in said casing, sealing means contactingthe outer surfaces of the arms of the U-shaped tongue, and invertedU-shaped spring clips mounted in the upper part of the casing havingdownwardly extending arms positioned over the arms of the tongue holdingthe sealingv means in contact with the arms of the tongue and urging thetongue outward.

3. In a weather seal for the lower edges of doors and the like, alongitudinally disposed casing rectangular shaped in cross section andhave ing a centrally disposed slot in a longitudinally disposed U-shapedment with bulging shoulders on the arms thereof positioned in andextending lengthwise of said casing and having an arcuatertongueextending through said slot, the arms of said sealing element above theshoulders having arcuate, upwardly and inwardly extending ends, inclinedv-platesxmounted in the lower dormers of the easing in engagement withthe upwardly-and. inwardly extending ends pith-e arms-of the sealin ele--ment, sealing strips :between rthe :inclined'plates and. easing, andmeans resiliently urging. the in- Mined plates" into engagement with thearms of the sealing element whereby the sealing element is urged.outward.
